WINDOW CONSTRUCTION.

To all whom it may concern:

Be it lmown that I, CHARLES W. RENNER, a citizen of the United States of America,

residing in Altoona, in the county. of BlairA and State yof Pennsylvania, have invented a certain new and useful Improvement in Window Construction, 'of which the following it.

ing is a true and exact description, reference being had to the accompanying drawings, which form a part thereof. c

4My present invention consists in certain .features of construction and-arrangement primarily devised for the purposeyof ob taining thoroughly tight joints between a window sash and its casing when th`e window is closed and for insuring easy operation ofthe window in opening and clos- Theinvention was is peculiarly adapted for use in connection cars. 1

The various features of constructlon and arrangement which characterize my lnven tion are pointed out w1th particularity 1n -the claims annexed to and forming a part of this specilication. l(

For a better understanding of the invention and the advantages possessed by it, reference should be had'to the accompany- 'Specification of Letters Patent.

l Application led 'February 11, 1911. Serial No. 697,899.

Aespecially devised, and

Awith the windows of railway steel passenger lng drawings and descriptive matter inj which I have illustrated and describedI forms of apparatus embodying my inven tion.

Of the drawings, Figure 1 is a partial side elevation of a steel passenger car. Fig. 2 j is a section on the line 2-2 of Fig. 1. Fig. 3 4

is a section taken similarly to Fig. 2l'of the weather strip and sash guide detached from the window casing. Fig. 4' is a view taken similarly to Fig. 2 but so as to show in secy tion both sashes of a double sash window construction. Fig. 5 is a section of one combined weatherI strip and sashguide employed in Fig. 4. Fig. Gis a section of a second form of weather strip and sash guide represents a car window A 'A' the sides, A2-

employed in Fig. 4. Fig. 7 is arView taken -similarly to Fig. 2 showing the use of the` invention'in connection with a metallic window sash. Y

In the drawings, and referring first to the construction showntin Figs. 1, 2 and 3, A

the bottom, and A2 the top ofthe window sash. As shown in Figs. 1, 2 and 3 the winvdow sash proper is formed of wood.` Thel Patented sept. 22, 19142 casing of the window is formed by metal posts B, "B, a metal sill D and a metal top piece P, all of the type in use in steel railceived in the channel B', a flange portion F4.

which abuts against the shoulder B2 of the l' window post B, and a connecting body portion which lies between the edge of the window sash and the corresponding faces of the window post B, and isformed with a fold.

The two sides F- and F2 of this fold approach closely to each other as .shown in Fig.3,and preferably with the side or web -F normally perpendicular. to the body .80 portion., and the side or web F2 slightly in- 5clined to the side F. The sides'of the sash' A are each formed with a narrow groove A4 in which the fold portion F F2 of the corresponding member F is received, and

.the parts areso proportioned-that'the sides F F2 of'eac-h -fold form a resilient rib compressed by the walls of the corresponding slot A2. L'lhe portion of the window sash between each slot A4 and the outer face of the sash is snugly received between the fold portion F F2 of the corresponding member F and its flange F4. Each window stri F is held in place by means of a correspon ing metal curtain guide strip C which enters the channel B and bears against the portion F3 of-the member Fand is held in place by" screws-C.

With the construction described, a perfectly tight joint between the" window sash and each window casing side or post B is obtained by the resilient engagement between the wall of the 4slot A4 and the fold sides F F2 of the member F.l At the same time there is no objectionable friction bel tween the sides of the window sash and the parts connected to the casing, since the strip F is formed of noncorroding resilient material and is comparatively smooth. The beads F 5 at the edge of each flange F4 fitder B2 of the window post prevents any ting snugly against the corner of the shouln objectionable admission of moisture between the weather strip F and the window post B, and I have found in the practical use of the invention that no appreciable ,corroding ofthe surface of the shoulder B2 has taken place in months of actual service.

In Figs. 4, 5 and 6, I have shown an arrangement for use in which there are two movable window 4sashes in each window l0 opening as shown in Figs. 4, 5 and 6. The two window sashes A andAA may each be identical with the sash A as shown in Figs. 1,

A2 and 3. v In Fig. 4, a combined weather strip and guide FA is employed which `may be identical in form with the strip F already described, except that the distance between the offset portion F? and the fold F F2 is .greater in Fig. 4 than in Figs. 1, 2 and 3. The window post BA in Fig. 4 differs from the window post B ofkFig. 2 only that the distance between the channel B and the shoulder B2 is greateriin Fig. 4 than in Fig..

2. In the construction shown Iin Figs. 4, `5 and 6, the grooves A4 in the sash sides A of the window -AA receive the fold portioh of a window strip and guide member H formed of noncorroding metal and differ-,-

ing from the members F and -FA principally inl that the strip H comprises nothing corresponding to the flange F, bead F 5, and body portion to the right ofthe fold H, H2, as viewed in Figs. 4 and 6. The o'set portions H3 'and F8 of the strips FA and H of Figs. 4, 5 and 6 are both secured in the '-85 channel B by the curtain strip C. In Fig.

. from that shown inFig. 1 in that the sash frame of the window AB shown, is in the form of a hollow metal structure. The metal sash isv provided in its side edges with grooves 'A4o corresponding to the grooves A* of the constructions previously described. f I n'Fi s. 1, 2 and 3, I have shown in detail,

sash loc applied directly to the window sash each comprising a casing Q, finger le:

vers Q', and a slidingbolt Q2. The latter is advantageously beveled at its operating end and adapted to, take in a 'correspondingly beveled socket formed in the curtain guide lstrip C,'the s'ash lock thus, tending to wedge --the sash away from the curtain guide strip.,

, The construction for forming a tight joint at the top of the window disclosed, but not claimed herein, is claimed in iny application Serial No. 681,909, iledMarch 6th, 1912.f`

Those skilled in the art will understandl that with the construction' describedf tight to receive a curtain guide member by w ich joints are obtained and .the opening and closing of the .window made easy, and that when the various weather strip members are madeof non-corrodible material,'the parts will last almost indefinitely. 7o While in 'accordance with the. rovisions of the statute I have illustrate and described the best forms of my invention now lmown to me, it will be apparent to those skilled in the art that -changesmay be' made 75 in the form of the apparatus disclosed without departingfrom the spirit of my invention, and that under some circumstances, certain Afeatures of the invention may be used with advantage without a correspondin use of other features.

aving now described my invention, what I claim as new and desire to secure by LettersA Patent, is: 1. A window construction comprising ir combination a sash having longitudinal grooves formed in its side edges a window casing receiving saidsash and havin me' tallic sides each formed with a shoul er at its outer edge, and achannel separated from said shoulder by a distance not less than the thickness of said sash, and a guide and weather strip for each casing side each formed of non-corroding metal with an oiset portion entering the channel and a iiange portion forming a facing forL the shoulder of the corresponding casing side and having an intermediate fold to provide a compressible ribentering the groove inthe corresponding side edge of the sash. l

2. A window construction comprisin in combination a sash having longitudinal grooves-formed in' its side edges, a window casing comprising metallic window posts each formed with a shoulder at its outer edge overlappingrthevouter face of the sash at its side wedges and also having a channel lformed in it at aldistance from said shoulder greater-than the thickness of said sash, and a combined sash guide .and lweather strip for each window post, each foigned'of noncorroding sheet metal and each comprising an offset portion enterin said channel, a flange portion forming a acing for' said shoulder and having a bead at its edge closing the outer edge of' the ljointbetween the ,body of said flange and -said shoulder, lsaid also a body\ ortion constrip comprisin l sald ian e necting said o set portion" an having a fold in it forming acompressib e 129 lrib entering the groove formed in theA corresponding side edge of the sash, the said channel-inl each window post being ada ted the corresponding strip' may be secured in place.
